Notes. Copying or filling a formula into all cells of a blank table column also creates a calculated column. If you type or move a formula in a table column that already has data, the AutoCorrect Options button appears so you can choose to overwrite the data to create a calculated column.o insert a new blank column in the table, right-click a cell in the table column to the right of which you want to insert the column, and click Insert Table Columns to the Left.
B cells are one of the two main types of lymphocytes. As opposed to T cells, B cells play a pivotal role in the humoral immune response, which is an antibody-mediated immune response. Each B-cell receptor (BCR) which sits on their cell surface, is specific for a particular antigen. The mature B cell expresses both the IgM and the IgD. The BCR is critical for B cell function, toward production of antibodies, as well as for their functioning as antigen-presenting cells (APCs).
T cells are named such because these lymphocytes mature in the thymus; B cells (named for the bursa of Fabricius in which they mature in bird species) are thought to mature in the bone marrow in humans. T and B lymphocytes differ from NK cells in that they are the principal cells involved in the adaptive immune system.he large granular lymphocytes are more commonly known as the natural killer cells (NK cells). The small lymphocytes are the T cells and B cells. Lymphocytes play an important and integral role in the body's defenses.
